Although it's really pretty unified in Spain: mainlines use broad gauge, some old local or mountain lines use meter gauge (includes the Metro in Valencia), and some other lines mostly modern subways as well as HSR use standard gauge.
Also Spain has one of the largest narrow-gauge networks in the world that doesn't constitute a mainline network. The narrow-gauge system in the north and northwest has over 1000 km of metre-gauge lines.
